United States Patent TRANSFUSION EQUIPMENT William C. Wootton, Centerville, Calif., assignor, by

mesne assignments, to United-Carr Fastener Corporation, Boston, Mass., a corporation of Delaware Application April 16, 1954, Serial No. 423,661

4 Claims. (Cl. 128-214) This invention relates generally to an assembly useful in making blood transfusions.

The object of the invention is to provide a combination tubing clamp and needle assembly which is adapted for economical manufacture so that it may be thrown away after one use.

A further object of the invention is to provide an assembly for use on a transfusion flask which provides means for both retaining the hypodermic needle and controlling the flow of blood therethrough.

Other objects will, in part, be obvious, and will, in part, appear hereinafter.

In the drawing:

Fig. 1 is a view in side elevation of a tubing clamp and needle assembly embodying the features of the invention;

Fig. 2 is a top plan view of the assembly of Fig. 1;

Fig. 3 is a bottom plan view of the assembly of Fig. 1',

Fig. 4 is a view in section taken on line 44 of Fig. 1;

Fig. 5 is a view of the assembly of Fig. l with the tubing in the closed position; and

Fig. 6 is a top plan view partly in section of the assembly of Fig. 5.

Referring to the drawing, there is illustrated a combination tubing clamp and needle assembly 10, which is adapted for use as a hand-grip device to be inserted through the stopper of a transfusion flask to control the flow of blood into the flask.

The assembly 10 comprises generally upper and lower colateral members 12 and 14 which are secured together at their end portions 16 and 18.

The members 12 and 14 have superimposed portions 20 and 22 adjacent the end 16, and spaced apart portions 24 and 26 adjacent the end 18. The superimposed por tions 20 and 22 are provided with longitudinal embossed channels 28 and 30, and the portion 24 of the upper member, which is arched upwardly away from the portion 26 of the lower members is provided with a longitudinally extending tapered opening 32.

A needle 34, having a tubing 36 assembled onto an end thereof, is disposed between the superimposed portions 20 and 22 in the channels 28 and so that the end portion surrounded by the tubing is firmly gripped by the portions 20 and 22 to retain the needle and tubing in assembly. A series of transverse embossments 37 may be provided in the channels to assist in preventing longitudinal movement of the needle therein.

The tubing 36 protrudes from between the superimposed portions about the projecting portion of the needle a sufiicient distance to enable a sterile cap 38 to be assembled therein to protect the needle. The tubing 36 also extends from between the superimposed portions into the space between the portions 24 and 26 and then through the tapered aperture 32, so that the flow of fluid through the tubing may be controlled by movement of the tubing in the aperture to restrict or completely close the tubing.

The assembly illustrated and described herein is particularly suited for rapid and economical manufacture, so that it may be thrown away after a single use, thereby eliminating problems of sterilizing the apparatus for reuse.

Since certain obvious modifications may be made in the device without departing from the scope of the invention, it is intended that all matter contained herein be interpreted in an illustrative and not in a limiting sense.

I claim:

1. A combination tubing clamp and needle holder, comprising a pair of colateral members having superimposed portions at one end, one of said members having a portion at the other end which is arched upwardly away from the other member, said superimposed portions having means for gripping a hypodermic needle, said upwardly arched portion having a tapered opening for receiving a tubing leading to the hypodermic needle.

2. A combination tubing clamp and hypodermic needle holder, comprising a pair of colateral members having superimposed portions at one end and spaced portions at the other end, cooperating longitudinal embossments in said superimposed portions to receive and grip a hypodermic needle and a tapered opening in one of said members in the spaced portion to receive a tubing therethrough.

3. A tubing clamp and hypodermic needle assembly, comprising a pair of colateral members having superimposed portions at one end and spaced portions at the other end, one of said members having a tapered opening in the portion spaced from the other member, said members having longitudinal embossments forming a channel therebetween and a needle and tubing assembly assembled with the members, said needle extending an appreciable distance into the end portion of the tubing, and said end portion being disposed in the channel and being gripped by the colateral members with the needle protruding therefrom, said tubing extending through said tapered opening.

4. A tubing clamp and hypodermic needle assembly, comprising a pair of colateral members having superimposed portions at one end and spaced portions at the other end, one of said members having a tapered opening in the portion spaced from the other member, said members having longitudinal embossments forming a channel therebetween, and a needle and tubing assembly assembled with the members, said needle extending an appreciable distance into the end portion of the tubing, and said end portion being disposed in the channel and being gripped by the colateral members, said needle protruding from between said members, at one end of the superimposed portions, said tubing protruding from the other end of the superimposed portion into the space between said spaced portions and extending through said tapered slot.
